Answer 1

After entering your proxy settings in settings.xml

<proxies>
<!-- proxy 
 | Specification for one proxy, to be used in connecting to the network.
 |  -->
<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username>DOMAIN\YOURID</username>
  <password>123456</password>
  <host>proxy.company.com</host>
  <port>8080</port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>

</proxies>

Check whether the below tag is having the value false in settings.xml

<offline>false</offline>

This helped me.

his issue is happening due to change of protocol from http to https for central repository. please refer following link for more details. https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required 

In order to fix the problem, copy following into your pom.ml file. This will set the repository url to use https.

<repositories>
        <repository>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
            <id>central</id>
            <name>Central Repository</name>
            <url>https://repo.maven.apache.org/maven2</url>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <releases>

            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
